Specification of Letters Patent. Patented; Jan. 11, 1910.

Application filed May 20, 1909. Serial No. 497,219.

To all whom it may concern:

Be it known that I, F RED CLARK, a citizen of the United States,residing at Vallonia Springs, in the county of Broome and State of NewYork, have invented certain new and useful Improvements in Horseshoes,of which the following is a specification, reference being had to theaccompanying drawings.

This invention relates to improvements in horseshoes and moreparticularly detachable calks therefor.

The object of the invention is to improve and simplify the constructionof devices of this character and provide one which will be inexpensiveto manufacture and to which the calks may be quickly and easily attachedand as readily removed and replaced.

With the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a bottom plan view of theimproved horseshoe having the calks applied thereto; Fig. 2 is alongitudinal section; Fig. 3 is a detail section taken on the line 3-3in Fig. 1; Fig. at is a detail section taken on the line 4t4: in Fig. 3;and Fig. 5 is a perspective View of one of the heel calks.

In the drawings 1 denotes the body of the horseshoe which is of ordinaryshape. Upon the under side of its toe portion is formed an enlargement 2in which is punched or otherwise formed a transverse opening 3 for thereception of the shank 4 of a right angular toe calk 5. The body of thecalk 5 extends downwardly and is tapered toward its lower end and theshank 4 extends rearwardly from the upper portion of the body 5 and atright angles thereto, as clearly shown in Fig. 2. The shank l isretained in the opening or socket 3 by a screw 6 passed upwardly throughregistering openings in the enlargement 2 and shank 4 and having itshead 7 countersunk in the bottom face of said enlargement. Each of therear ends or heel portions of the shoe is also provided upon its underface with an enlargement 8 having a transverse notch or slot 9 extendinginwardly from its extremity and adapted to receive the right angularshank 10 of a heel calk 11. These heel calks are similar to the toe calkand the body portion of each extends downwardly and is tapered, asclearly shown in Figs. 2, 3 and 5. A screw 12 is used for fastening eachheel calk in its recess or slot 9, said screw having its head 13countersunk in the bottom face of one of the enlargements 8, as shownmore clearly in Fig. 3. For the purpose of preventing the heel calk fromturning on the screw 12, the back of the slot or recess 9 is formed witha tapered socket let to receive a beveled and tapered end 15 on theshank 10 of the heel calk.

This construction insures an effective attachment of the heel calks withthe shoe so that they cannot possibly turn or twist and at the same timeallows the heel portions of the shoe to be easily shaped at a small costfor the reception and attachment of the heel calks.

Having thus described the invention what is claimed is:

The herein described horseshoe having an enlarged heel portion formedwith a transverse recess extending from its extremity inwardly and fromone side edge to-the other, said recess having its back formed withconverging top and bottom portions, and converging end portions wherebya pyramidal socket is produced in said recess, said enlarged heelportion of the shoe being also formed with a screw threaded openingintersecting the recess and formed at one end with a countersink, aright angular calk having a tapereddepending outer end, and arectangular inner end formed in its central portion with a screwthreaded opening to register with the one in the heel portion of theshoe, the extremity of said rectangular end of the calk beingpyramidally shaped to enter said socket in the recess of the heelportion of the shoe, and a screw arranged in said alining screw threadedopenings and having its head flush with the bottom face of the enlargedportion of the shoe, said screw retaining the calk in the shoe and theengagement of the pyramidal-shaped extremity of the calk with saidsocket in the recess of the heel portion of the shoe preventing saidcalk from turning axially on the screw.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.

FRED CLARK.
